SPECIFICATION forming part of Letters Patent No. 471,623, dated March 29, 1892.

Application filed September 23, 1889. Serial No. 324,858. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. SHAW, a citizen of the United States, residing at Del Norte,

in the county of Rio Grande and State of Colorado, have invented certain new and useful Improvements in Sack-Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it-appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in sack-fasteners; and the obj ect of myimprovement is to provide a fastener for ore, grain, and other sacks which shall take the place of the present method of sewing or tying the top of the sack with twine, my improved fastener being also provided with a suitable handle, by means of which the sack may be taken in the hand and easily carrieda fastener of the class and for the purpose mentioned which shall be of simple and economical construction, durable, easily operated, reliable, and effective; to which ends my invention consists of the features hereinafter described and claimed.

In the drawings is illustrated an embodi ment of my invention, in which drawings- Figure 1 is a perspective view of the device when open. Fig. 2 is a top or plan view of the same. Fig. 3 is a top View of the device when closed; and Fig. 4 is a transverse section taken on the line m m, Fig. 2.

In the views let the reference-numerals 1, 2, 3, and 4 indicate the four sides of the device, which when open is shown in the drawings tobe rectangular in shape, though it might be square, or there might be any greater number of sides than four. The extremities of the parts 1, 2, 3, and 4 are connected by means of suitable hinges 5, 6, 7, and 8 and adapted to .close up readily, as shown in Fig. 3, when two diagonally-opposite hinges or corners are pressed upon. provided with longitudinal corrugations on their inner surfaces, as shown in Fig. 4. The beads and grooves forming these corrugations are alternately arranged opposite each other on the parts, so that when the device is closed the mouth of the sack will be securely held These parts are 9 is provided with a small hole 13 in its outer extremity, adapted to receive a key for locking the device when closed. The pin 10 is provided with a notch 14, adapted to engage a steel spring 15, secured to part 4, as shown. Pin 9, with its key-hole, and pin 10, with its notch and spring, illustrate two methods of.

securing the device in the closed position.

The parts 1, 2, 3, and 4 of the device are provided with a plural number of small apertures 16, extending through the parts, their object being to provide a means by which the device may be fastened to the top of the sack either by sewing or by the use of small metal fastenings, the material of the parts being sufficiently cut away on the inside surface and on the line of the openings 16 to allow room for that part of the twine or other material used which must lie on the inner surface of the parts without lessening the security of the fastener.

To one of the parts, as part 2, is secured a suitable handle 17, (shown in the drawings as hinged to the part 2 by means of lugs 18,)pro vided with eyes, through which one side of the handle passes. This handle may be of any suitable shape, secured to the fastener in any desired manner, and located thereon wherever deemed most convenient.

The shape of my improved device when open, as before stated, may be that of any figure having four or more sides, though I prefer the rectangular shape, as shown in the drawings.

In the use of improved device it is secured to the top of the sack by sewing through the apertures 16 or by any other suitable means. The device is closed by pressing upon the diagonally-opposite hinges or corners 6 and 8, causing the device to take the form shown in Fig. 3, closing the mouth of the sack, the pins 9 and 10 entering apertures 11 and 12, respectively. The device is held in the closed position by the use of one or more springs 15, which engage notches in one or more pins 10, or by the use of suitable keys placed in apertures in one or more pins 9, an aperture 13 being shown in pin 9 for this purpose.

Having thus described my invention, what I claim is 1, A sack-fastener composed of parts 1, 2, 3, and 4, suitably hinged together and corrugated longitudinally on their inner surfaces, the beads and grooves of the corrugations being arranged alternately on the parts opposite each other when the device is closed, the parts being provided with a plural number of apertures 16, and means for holding the parts securely in the desired position when closed,

substantially as described.

2. In a sack-fastener, the combination, with parts 1, 2, 3, and 4, suitably hinged together and corrugated longitudinally on their inner surfaces, the beads and grooves of the corrugations being arranged alternately on the parts opposite each other when the device is closed and provided With means for attaching the device to the sack, of means for securing the parts in the closed position, said means conslsting of one or more pins 9, provided with holes 13,0ne or more apertures 11, adapted to receive the pins, and suitable keys adapted to engage holes 13, substantially as described.

3. A sack-fastener consisting of parts 1, 2, 3, and 4, said parts being hinged together and corrugated longitudinally ontheir inner surfaces, the beads and grooves of the corrugations being arranged alternately on the parts opposite each other when the device is closed, means for attaching the device to the sack, and means for retaining the parts in the closed position, substantially as described.

4. A sack-fastener composed of parts 1, 2, 3, and 4, suitably hinged together and corrugated longitudinally on their inner surfaces, the beads and grooves of the corrugations bein g arranged alternately on the parts opposite each other when the device is closed, means for attaching the device to the sack, means for retaining the parts in the closed position, and a handle secured to the device in any suitable manner, substantially. as described.

5. A sack-fastener composed of four or more parts suitably hinged together and corrugated longitudinally on their inner surfaces, the beads and grooves of the corrugations being arranged alternately on the parts opposite each other when the device is closed and adapted to close readily upon the mouth of the sack, and means for securing the parts in the closed position, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN H. SHAW.
